Two carts on a friction free air track make a head-on collision as shown. If the carts stick together on collision, what will their final velocity (note signs) be? The car moving right has a speed of 30cm/s and a mass of 2M, the car moving to the left has a speed of "-"40 cm/s with a mass of 1M

+33 cm/s+6.7 cm/s     -6.7 cm/s+34 cm/s-33 cm/s

Answer #1

The law of conservation of linear momentum states that if no external forces act on the system of two colliding objects, then the vector sum of the linear momentum of each body remains constant and is not affected by their mutual interaction. ... Therefore, 'P' is constant or conserved.
